本發明一較佳實施例之光學檢測裝置,係一種將由軟性素材而成之檢測基片10以真空加以吸附、固定,以對其執行視覺檢測者,包含:一檢測台100,係由光穿透性材質而成,供裝載檢測基片10,另形成有沿著上面邊緣方向往下凹入之容置凹槽110,並藉由貫通該容置凹槽110與下面形成流路120;一固定架200,係供支撐該檢測台100之側面或上面;一吸板300,係由多孔質陶瓷材質而成,供插設於該檢測台100之容置凹槽110;一真空模組400,係於該流路120施加真空壓,使該吸板300上之檢測基片10作吸附;一背光元件500,係由該檢測台100之下方將光照射於檢測台100上之檢測基片10;一成像裝置600,係裝設於該檢測台100之上方,供擷取裝載於該測台100之檢測基片10之影像。An optical detecting device according to a preferred embodiment of the present invention is a method in which a detecting substrate 10 made of a soft material is adsorbed and fixed by vacuum to perform visual inspection thereon, comprising: a detecting station 100, which is worn by light. a permeable material for loading the detecting substrate 10, and a receiving recess 110 recessed downwardly along the upper edge direction, and forming a flow path 120 through the accommodating recess 110 and the lower surface; The fixing frame 200 is for supporting the side or the top of the detecting table 100; a suction plate 300 is made of a porous ceramic material for inserting into the receiving groove 110 of the detecting table 100; a vacuum module 400 Applying a vacuum pressure to the flow path 120 to cause the detection substrate 10 on the suction plate 300 to be adsorbed; a backlight element 500 is a detection substrate on which the light is irradiated on the detection table 100 from below the detection table 100. An imaging device 600 is mounted above the inspection station 100 for capturing images of the detection substrate 10 mounted on the measurement platform 100.

本發明所稱檢測基片10,係可由軟片、設有孔之基板、紙、布、薄板、薄膜等習用各類板形素材所構成。The detecting substrate 10 of the present invention may be composed of a film, a substrate provided with a hole, a paper, a cloth, a thin plate, a film, and the like, and various types of plate-shaped materials.

該檢測台100,係由光穿透性材質而成,供裝載檢測基片10,其上面形成有沿著上面邊緣方向往下凹入之容置凹槽 110,並藉由貫通該容置凹槽110與下面形成流路120,而該檢測基片10則安裝於其上面,以供檢測。The detecting station 100 is made of a light transmissive material for loading the detecting substrate 10, and the receiving surface is formed with a receiving recess recessed downward along the upper edge direction. 110, and forming a flow path 120 through the accommodating recess 110 and the lower surface, and the detecting substrate 10 is mounted thereon for detection.

該檢測台100,係應由透明素材所構成,如玻璃、壓克力等,以能夠讓配置於其下方之背光元件500之光穿透。此外,該檢測台100之形狀,可包含正方形、長方形、圓形等,以對應於預計進行檢測之檢測基片10之形狀為較佳。茲舉一例加以說明,當該檢測基片10為正方形時,該檢測台100亦呈正方形。以在一檢測台100檢測一檢測基片10為原則,惟基於提升檢測速度,可在一檢測台100裝載複數個檢測基片10且進行檢測。後者,該檢測台100之大小或形狀,應以具有足夠空間方式加以搭配,以能夠裝載複數個檢測基片10。The inspection station 100 should be composed of a transparent material such as glass, acryl or the like to allow light of the backlight element 500 disposed under it to penetrate. Further, the shape of the inspection table 100 may include a square, a rectangle, a circle, or the like, preferably in accordance with the shape of the detection substrate 10 which is expected to be detected. As an example, when the detecting substrate 10 is square, the detecting station 100 is also square. Based on the principle that a test substrate 100 detects a test substrate 10, based on the lift detection speed, a plurality of test substrates 10 can be loaded on a test stand 100 and detected. In the latter case, the size or shape of the inspection station 100 should be matched in a sufficiently spatial manner to enable loading of a plurality of detection substrates 10.

另一方面,該檢測台100之上面邊緣,形成有往下方凹入之容置凹槽110,並貫穿該容置凹槽100與下面形成流路120。該容置凹槽110,其係供安裝吸板300(後續作補充說明)之空間;流路120則係供作於該吸板300施加真空壓所需之通路。該容置凹槽110與流路120,其寬度不相同,可藉階梯形加以相連,以供其兩者間形成卡榫,此時,該流路120之寬度比該容置凹槽110之寬度較窄為較佳。茲舉一例加以說明,該容置凹槽120可沿著正方形檢測台100之邊緣形成為正方形,而所有容置凹槽110,則可為藉由連接成一體,使其內部形成封閉空間之結構,但可為由複數個容置凹槽110分別依個別區間呈各容置凹槽110之間呈封閉之結構。On the other hand, the upper edge of the inspection table 100 is formed with a receiving recess 110 recessed downward, and a flow path 120 is formed through the receiving recess 100 and the lower surface. The receiving recess 110 is a space for mounting the suction plate 300 (described later in detail); the flow path 120 is for providing a passage required for the suction plate 300 to apply a vacuum pressure. The accommodating recess 110 and the flow path 120 have different widths and can be connected by a step shape for forming a latch therebetween. At this time, the width of the flow path 120 is larger than that of the accommodating recess 110. A narrower width is preferred. As an example, the accommodating recess 120 may be formed in a square shape along the edge of the square detecting table 100, and all the accommodating recesses 110 may be a structure in which the inside is formed into a closed space by being integrally connected. However, the plurality of accommodating recesses 110 may be respectively closed between the accommodating recesses 110 according to the respective intervals.

該固定架200,係藉由支撐該檢測台100之側面或下面,進而扮演將該檢測台100連接於本體700之角色。該固定架 200,係可為同夾具(jig)之結構,並可將該檢測台100固定於呈桌形結構之本體700。此時,該本體700之中心部位,可形成一個中空的空間,供插入該檢測台100。The fixing frame 200 plays the role of connecting the detecting table 100 to the body 700 by supporting the side or the bottom of the detecting table 100. The holder 200, which may be the same jig structure, and the test stand 100 may be fixed to the body 700 in a table-like structure. At this time, a central portion of the body 700 can form a hollow space for insertion into the inspection station 100.

該吸板300,係由多孔質陶瓷素材所構成,並插設於該檢測台100之容置凹槽110。該吸板300之形狀,可對應於該容置凹槽110之形狀,以供插入該容置凹槽110內。茲舉一例加以說明,該容置凹槽110呈長方形,而該吸板300亦呈長方形。因此,該檢測台100之上面,係該吸板300沿著其邊緣呈外漏狀態,而可透過外漏之該吸板300使該檢測基片10加以固定。若該吸板300由多孔質陶瓷素材所構成,空氣便會透過形成於陶瓷之微細空隙吸入,進而產生往該吸板300上面之吸附力,並透過該吸附力使該檢測基片10加以固定。The suction plate 300 is made of a porous ceramic material and is inserted into the receiving groove 110 of the inspection table 100. The shape of the suction plate 300 can correspond to the shape of the receiving groove 110 for insertion into the receiving groove 110. As an example, the receiving recess 110 has a rectangular shape, and the suction plate 300 has a rectangular shape. Therefore, on the upper surface of the inspection table 100, the suction plate 300 is in an external leakage state along the edge thereof, and the detection substrate 10 can be fixed by the suction plate 300 which is leaked externally. If the suction plate 300 is made of a porous ceramic material, air is sucked through the fine voids formed in the ceramic, thereby generating an adsorption force on the suction plate 300, and the detection substrate 10 is fixed by the adsorption force. .

本發明之較佳實施例,其中形成於該檢測台100之容置凹槽110之深度(D),與插設於該容置凹槽110之吸板300之厚度(T)相同,進而使該檢測台100與吸板300之上面以平面方式加以連接。In a preferred embodiment of the present invention, the depth (D) formed in the receiving recess 110 of the detecting station 100 is the same as the thickness (T) of the suction plate 300 inserted in the receiving recess 110, thereby The test stand 100 is connected to the upper surface of the suction plate 300 in a planar manner.

即,當該吸板300與檢測台100無法以平面加以連接時,便有可能會發生其上面所搭載檢測基片10之形狀變形或吸附力減弱等之問題。因此,將該吸板300與檢測台100以水平方式加以連接,以避免發生如上所述之問題。That is, when the suction plate 300 and the inspection table 100 cannot be connected in a plane, there is a possibility that the shape of the detection substrate 10 mounted thereon is weakened or the adsorption force is weakened. Therefore, the suction plate 300 and the inspection table 100 are connected in a horizontal manner to avoid the problem as described above.

該真空模組400,係具有將真空壓施加於該流路120,使該吸板300上之檢測基片10作吸附之功能。當該真空模組400與流路20相連,藉以施加真空壓時,便由插設於該容置凹槽110之吸板300產生吸附力。The vacuum module 400 has a function of applying a vacuum pressure to the flow path 120 to adsorb the detection substrate 10 on the suction plate 300. When the vacuum module 400 is connected to the flow path 20, when the vacuum pressure is applied, the suction force is generated by the suction plate 300 inserted in the accommodating recess 110.

本發明之較佳實施例,其中該真空模組400,係可包含:一真空軟管410,其一端供與該檢測台100之流路120相連;一開關閥與真空泵浦420,其與該真空軟管410相連,藉以施加真空壓。In a preferred embodiment of the present invention, the vacuum module 400 can include: a vacuum hose 410 having one end connected to the flow path 120 of the inspection station 100; an on-off valve and a vacuum pump 420, Vacuum hoses 410 are connected to apply vacuum pressure.

因此,當該真空泵浦420運轉時,該流路120與容置凹槽100之空氣便會透過該真空軟管410向外流出,藉以產生真空壓,同時在該吸板300產生吸附力。Therefore, when the vacuum pump 420 is operated, the flow path 120 and the air accommodating the groove 100 will flow outward through the vacuum hose 410, thereby generating a vacuum pressure, and at the same time, an adsorption force is generated in the suction plate 300.

該背光元件500,係配置於該檢測台100之下方,供作將光照射於該檢測台100上之檢測基片10之光源。The backlight element 500 is disposed below the detection stage 100 and serves as a light source for detecting the substrate 10 on the detection stage 100.

因此,由該背光元件500照射之光,便會通過該檢測台100,並穿透裝載於其上面之該檢測基片10,藉以輸往該成像裝置(600),進而能夠檢測該檢測基片10之不良與否。茲舉一例加以說明,可檢測鑽孔於該檢測基片10之複數個孔或軟片上所形成花樣部之形狀,與該孔是否位於正確位置或其形狀影像之不良與否。Therefore, the light irradiated by the backlight element 500 passes through the detecting station 100 and penetrates the detecting substrate 10 mounted thereon, thereby being sent to the image forming apparatus (600), thereby being capable of detecting the detecting substrate. 10 is not good or not. As an example, the shape of the pattern formed on the plurality of holes or films of the detecting substrate 10 can be detected, and whether the hole is in the correct position or the image of the shape is defective or not.

該成像裝置600,係配置於該檢測台100之上方,供擷取裝載於該檢測台100之檢測基片10之影像者,包含相機。透過該成像裝置600所擷取之影像,可執行影像分析及辨別不良與否。The imaging device 600 is disposed above the detection platform 100 and includes a camera for capturing images of the detection substrate 10 mounted on the detection platform 100. Through the image captured by the imaging device 600, image analysis and discrimination can be performed.
